Following the COVID-19 pandemic, there has been a significant global increase in mental health disorders, predicted to rise even further. University students are particularly affected due to their high prevalence of and sensitivity to mental health-related problems. Specifically in the Netherlands, this is further exacerbated by the ongoing housing crisis, which forces many students into poor-quality, cramped accommodations. This research explores how phenomenological principles can inform student housing design to enhance mental well-being. Using a literature review, case studies, interviews, and participatory sketching, the study identifies key architectural elements that support mental well-being. Among these, the most important findings highlight the importance of accessible and visible greenery from the dwelling, ample direct sunlight, quiet bedrooms, communal spaces and the presence of a courtyard.
